While many people are well familiar with "taking a screen-shot of your PC", some others might wonder what it is. On an Windows PC, the "Print Screen" feature can either capture the entire screen of your PC, or an individual window. This is a simple but very helpful tip. Once you know about it, you will find it very useful in many situations, i.e. when you need to show a tech-support person an error alert on your screen, or a sample screen of an application software...
The following instructions will show you how to capture a screen shot of your entire desktop or an individual window. On most standard keyboards, the print screen button is often identified as "Print Scrn".

To capture a screen shot of your entire desktop:

Hit "Print Screen" key on your keyboard (or "Print Scrn").

Open an image editor (i.e. Photoshop, Paintshop, or the Windows built-in "Paint").
